NHTSA Complaint #11421147 — 2016 CHEVROLET MALIBU

I have a 2016 Chevrolet Malibu and while driving on the highway, my engine light came on and my speed decelerated from 65 mph to 40. I took my car for a diagnostic test and the results were Trouble Codes: P2138, U0401-71 and C0242-00. I have done my research and from what I have found so far, is that several people have made Youtube videos about these codes, complaints and complaints on this website as well, and it has come to my understanding, that if enough people complain that this can be a safety issue, then maybe the "POWERS THAT BE", will help with this issue and possibly resolve it. This is and can be dangerous for an individual to drive at the average speed on most U.S. highways, 65, and they decelerate without warning down to 40 mph. I'm not sure why anyone does not se the dangers in this situation, especially with other motorists on the road driving at speeds of up to 70 mph, sometimes 75 mph. If I have vehicles behind me driving 65 or more and my vehicle decides to decelerate because of a sensor failure, the vehicle behind me is not going to know that there is a problem and may not have enough time to react before causing an accident. I am adding my concern not only to many individuals who have reported the same or similar experience , but in hopes that this issue would gain more attention.
